Pen enrichment for broiler chickens is one of the potential strategies to stimulate locomotion and consequently contribute to better leg health and welfare. This study was designed to evaluate effects of using a plethora of pen enrichments (barrier perches, angular ramps, horizontal platforms, large distance between feed and water and providing live Black Soldier fly larvae in a dustbathing area) on tibia characteristics, locomotion, leg health and home pen behaviour of fast and slower-growing broiler chickens. The experiment was set up as a 2 x 2 factorial arrangement with a total of 840 male broiler chickens in a complete randomized design (7 pens per treatment and 30 chickens per pen) with the following treatments: 1) pen enrichment (enriched pen or non-enriched pen); 2) broiler strain (fast-growing Ross 308 or slower-growing Hubbard JA 757). Home pen behaviour and use of enrichment were observed. At approximately 1400 and 2200 g body weight, two chickens per pen were randomly selected and slaughtered, to investigate tibia morphological, biophysical and mechanical characteristics and leg health. Pen enrichment positively affected tibia biophysical characteristics, e.g., osseous volume (Δ = 1.8 cm3, P = 0.003), total volume (Δ = 1.4 cm3, P = 0.03) and volume fraction (Δ = 0.02%, P = 0.002), in both fast and slower-growing chickens, suggesting that pen enrichment particularly affects ossification and mineralization mechanisms. Accordingly, locomotion and active behaviours were positively influenced by pen enrichment. However, pen enrichment resulted in lower body weight gain in both strains, which might be due to higher activity or lower feed intake as a result of difficulties of crossing the barrier perches. Regarding the strain, slower-growing chickens showed consistently more advanced tibia characteristics and more active behaviour than fast-growing chickens. It can be concluded that pen enrichment may lead to more activity and better bone development in both fast and slower-growing chickens.

Pen enrichment for broiler (meat-type) chickens is one of the potential strategies to stimulate locomotion and consequently contribute to leg health and welfare. This study was designed to evaluate effects of using a plethora of pen enrichments (barrier perches, angular ramps, horizontal platforms, large distance between feed and water and providing live Black Soldier fly larvae in a dustbathing area) on tibia characteristics, locomotion, leg health and home pen behaviour of fast and slower-growing broiler chickens. The experiment was set up as a 2 x 2 factorial arrangement with a total of 840 male broiler chickens in a complete randomized design (7 replicates per treatment and 30 chickens per replicate) with the following treatments: 1) pen enrichment (enriched pen or non-enriched pen); 2) broiler strain (fast-growing Ross 308 or slower-growing Hubbard JA 757). Home pen behaviour and use of enrichment were observed. At approximately 1400 and 2200 gram body weight, two chickens per pen were randomly selected and slaughtered, to investigate tibia morphological, biophysical and mechanical characteristics and leg health. Pen enrichment positively affected tibia biophysical characteristics, e.g., osseous volume (?=1.8 cm3, P=0.003), total volume (?=1.4 cm3, P=0.03) and volume fraction (?=0.02 %, P=0.002), in both fast and slower-growing chickens, suggesting that pen enrichment particularly affects ossification and mineralization mechanisms. Accordingly, locomotion and active behaviours were positively influenced by pen enrichment.

ABSTRAK. Penelitian ini bertujuan untuk mengevaluasi performa tiga strain ayam broiler yang umumnya dipelihara di Aceh. Materi yang digunakan adalah 150 ekor anak ayam broiler (DOC) strain Cobb 500, CP 707, dan MB 202 masing-masing berjumlah 50 ekor. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dan 5 ulangan. Setiap ulangan merupakan unit percobaan yang masing-masing terdiri dari 10 ekor anak ayam. Perlakuan adalah tiga strain ayam broiler: Cobb 500 (P1), CP 707 (P2), dan MB 202 (P3). Parameter yang diamati meliputi pertambahan berat badan, konsumsi ransum, konversi ransum (FCR), mortalitas, dan Income over Feed and Chick Cost (IOFCC). Hasil penelitian memperlihatkan performa broiler dipengaruhi oleh jenis strain. Strain MB 202 dan CP 707 memiliki bobot badan akhir (6 minggu) dan konsumsi ransum nyata (P0,05) lebih tinggi daripada Cobb 500. Angka konversi ransum tidak memperlihatkan perbedaan yang nyata antara ketiga strain pada semua umur panen. Nilai IOFCC tertinggi dipengaruhi oleh jenis strain dan lama pemeliharaan. Dari hasil penelitian dapat disimpulkan bahwa performa broiler dipengaruhi oleh kemampuan adaptasi strain terhadap iklim setempat (pesisir Aceh) pada periode berbeda-beda yang dapat memengaruhi tingkat keuntungannya. Strain Cobb 500 memiliki kemampuan adaptasi lebih baik selama periode awal, sedangkan CP 707 dan MB 202 selama periode akhir. (Evaluation of performances and income over feed chick cost (iofcc) of three broiler chicken strains commonly marketed in Aceh) ABSTRACT. The study aimed to evaluate the performances and Income over Feed and Chick Cost (IOFCC) of three broiler chicken strains commonly marketed in Aceh. As many as 150 chicks of three different broiler strains (50 birds each) were used in this study. The study was performed into Completely Randomized Design (CRD) consists of 3 treatments and 5 replications creating 15 experimental units containing 10 birds each. The treatments were 3 different strains of broiler chickens i.e. Cobb 500, CP 707, and MB 202. The birds were reared up to 6 weeks to expose their performances recorded as final body weight, body weight gain, feed intake, and feed conversion, as well as mortality. Economic value was evaluated by calculating IOFCC. Results of study showed that performances of broilers were significantly (P0,05) influenced by the strains. Strains MB 202 and CP 707 represented more superior than Cobb 500 for 5−6 weeks of raising periods. However, the later was not inferior during initial phase close to 4 weeks. There were no significant differences in FCR among all strains for different ages. The IOFCC related to the strains and their marketing ages. The highest IOFCC was obtained by Cobb 500, CP 707, and MB 202 as they were sold at the ages of 4, 5, and 6 weeks, respectively. In conclusion, the achievements of the performances in various broiler strains were affected by the site climate (Aceh) in different stages of their ages. Cobb 500 had proper adaptation during starter, while CP 707 and MB 202 appeared seem to be better than Cobb 500 during finisher period.

An experiment was conducted to study the effect of <em>Zataria multifora</em> (ZM) on the performance and liver histopathology of broiler chickens contaminated with aflatoxin B1 (AFB1). One hundred and sixty Ross 308 male broilers (one-day-old) were divided into four treatment groups with four replicates with 10 birds in each replicate. The chickens were reared on the floor for 35 days. The groups were contaminated with AFB1 at two different concentrations,<em> i.e.,</em> 0 and 1000 ppb, and fed ZM in their feed at the concentrations of 0 and 20 gr Kg 1. The evaluated performance parameters were subjected to a completely randomized design with a 2×2 factorial arrangement of the treatments using SAS software (version 9/1). AFB1 had a statistical lowering effects on the feed intake, body weight, body weight gain and average weight of the carcass, thigh, chest, bursa of fabricius, back and neck. Also, the weights of liver, gizzard, pancreas, proventriculus, abdominal fat, full intestine, and heart were increased with AFB1 (P&lt;0.05). In histopathological evaluations, the liver of chickens that received feed containing AFB1 showed multifocal and varied cytoplasmic vacuolization, severe fatty change, degenerating foci, fibrosis of the portal regions, and bile duct hyperplasia. The variables that were evaluated in this study showed that ZM had significant efficacy in diminishing the aflatoxins negative effects on the chickens.

The aim of this study was to determine the calcium requirements of broiler chickens in starter phase with the addition of phytase enzyme. This experiment used 1,200 broiler chickens (mixed sex) for 21 days rearing period in a closed house. The basal diets was corn and soybean meal which contained 0.097% Ca and 0.123% P-av. The treatments consisted of 6 diets treatment: P1 (basal diet with the addition of 0.42% non-phytate phosphorus (NPP), and then P2 to P6 were basal diet with the addition of 0.22% NPP and 1,000 FTU/kg phytase and the addition of calcium (Ca) at different levels: 0.82% (P2); 0.74% (P3); 0.66% (P4); 0.58% (P5) and 0.50% (P6). The growth performance, feed efficiency, and bone mineralization parameters were studied using Oneway ANOVA in a Completely Randomized Design. Duncan's new Multiple Ranges Test was used to separate means with significant differences. Results showed that 0.90% Ca supplementation without phytase and the reduction levels of Ca from 0.82% to 0.50% increased the amount of feed consumed by birds in all growth phases (P<0.05). The addition of phytase had beneficial effects on increasing body weight (P<0.05) and average of body weight gain (P<0.05), and decreased the value of FCR in 11 - 21 days and 1 - 21 days. The addition of phytase increased protein and energy consumption, followed by increased in the value of PER and  EER (P<0.05). When phytase was added in the diets, reduction levels of Ca in the diets up to 0.50% did not give any adverse effect on the tibia bone ash. It can be concluded that feeding with phytase can sustain growth performance, feed efficiency, and bone mineralization.

An immunomodulator is a natural body defence mechanism due to the stimulation of objects/ environments, both specific and non-specific by means of cellular and humoraldefence. The objective of the study was to prove the immunomodulation ability of broiler chickens up to age 35 days that dietary fed various wheat pollard based rations. The design used in the study was a complete randomized design with six treatments and three replications. The treatment of broiler rats consisted of BR-IAJ (T0), control feed with wheat pollard base (T1), control feed with wheat pollard base plus probiotic (T2), wheat pollard based feed steamed (T3), fermented wheat pollard based feed 40% (T4 ) and fermented wheat pollard based feed 60% (T5). The rations used contained 20,5-22,5% protein with 2900-3100 Kcal metabolic energy. Lohman MB 202 Platinum from PT. Japfa Comfeed used in research with average day old chick (DOC) weight of 36,39 + 2,45 g. Parameters observed included body weight, feed intake, feed conversion ratio (FCR), relative weights of liver organ, thymus, lymph and bursa fabricius. The results showed that wheat pollard-based rations had a significant effect (p <0,05) on the relative weight of liver organ, body weight, FCR and ration consumption, but did not affect the relative weights of spleen organ, thymus and bursa fabricius. The mean relative weight of consecutive liver as follows: 2,47 g (T0), 2,83 g (T1), 3,40 g (T2), 2,99 g (T3), 3,15 g (T4) and 3,06 g (T5). The average body weight, consumption and FCR rations were as follows: 1415,24 g; 136,45 g/day; 2,03 (T0), 775,04 g; 125,19 g/day; 3,40 (T1), 813,17 g; 129,86 g / day; 3,36 (T2), 792,89 g; 128,14 g /day; 3,54 (T3), 892,91 g; 138,33 g /day; 3,27 (T4), 969,56 g; 155,52 g/day; 3,37 (T5). The conclusion of the study was that the ration with the addition of wheat pollard 60% was able to provide an increase in body weight gain and the best immunomodulation seen from the aspect of the proportion of immunomodulating organs to the growth of broiler chickens.

Poultry products from such as broiler chicken usually contain residues because in the maintenance of chicken used medicinal ingredients, both to prevent disease and increase body weight. This study was aimed to determine the ability of pegagan plan (Centella asiatica) as natural feed additive to stimulate the body weight of chicken. The experiment was run in completely randomized design which consist of 4 feed treatments and 5 replications. Level used of A = without pegagan powder; B = 1.5% pegagan powder; C = 3% pegagan powder dan D = 4.5% pegagan powder. The result shown that body weight was significantly different (P &lt; 0.05) but not for HI ND was no significantly different (P &gt; 0.05). The higher of body weight of chicken shown in D parameter (level 4.5% pegagan powder) was 944.0 g. Pegagan influences a vasodilation to increase blood flow of chicken which has an impact on increasing body metabolism, so that it becomes an acceleration of body weight gain in broiler chickens.

Cassava has the potential use to replace corn as an energy source in poultry feed.However, the level of substitution is not optimal because of the difference ratio ofamylose and amylopectin in maize and cassava. This study aimed to examine the effectof cassava flour with addition of isoamylase as a corn substitute in the ration on theperformance of broilers. The material used in this study was 150 male day-old chickenbroiler which were randomly divided into 3 treatments and 5 replications. Thetreatments were P0: 50% corn in the ration (control); P1: Substitution of 50% of cornby cassava flour; P2: Substitution of 50% of corn by cassava flour which contained0.14% isoamylase. The variables measured were feed intake, body weight, weight gain,feed conversion ratio, income over feed and chick cost and mortality rate. Data from thecomplete randomized design were analyzed using Analysis of Variance, the significantresults between the treatments were obtained by Duncan Multiple Range Test. Theresults showed that the substitution of corn by cassava flour without and with 0.14%isoamylase was not significantly affect final body weight, body weight gain, feed intakeand feed conversion ratio. The most profitable Income over feed cost obtained was thetreatment of P2 that is Rp 6,543.50. It can be concluded that the corn substitution bycassava flour without and with addition of 0.14% isoamylase was able to produce thesame performance as broiler chickens fed with corn in the ration for five weeks of thestudy. Key words: broiler, isoamylase, cassava flour, performance

Commercial Feeds

This study aims to examine the different weighting and different types of commercial feeds on the growth of broiler chickens. The study was prepared based on Completely Randomized Design (RAL) of 4 x 3 and 3 replication factorial patterns. The first factor is Grouping Cut Off (600 - 1000 grams or ± 800 g, 1,100 - 1300 g or ± 1,200 grams, 1,400-1,700 or ± 1,600 grams, 1,800 - 2200 g or ± 2,000). The second factor is the type of commercial feed / ration from different factories (AB1, BP11 and P11). Parameters measured include: feed intake, drinking water consumption, body weight gain, feed conversion and final cutting weight. The results of this study indicate that the use of commercial BP-11 feed on various commercial broiler feed factors resulted in increased body weight, better feed conversion compared with AB-1 and P-1 feed types. While the cut weight factor significantly affect the consumption of feed as weight gain and cut weight. At the cut weight of 1100-1500 grams, the average feed conversion produced is the lowest that is 1.26 which indicates that this cut weight is most favorable with the smallest feed efficiency. Keywords:   cutting weight, commercial feed, growth, feed consumption, average daily gain, feed conversion, broiler chicken
